Abstract

Metal(loid) soil pollution causes environmental and health issues, and thus those sites need to be remediated. This can be done through phytostabilization, in combination with biochar amendment. The objectives were to investigate the potential of Salix viminalis L. associated with Trifolium repens L. for the phytostabilization of biochar-amended contaminated soils by assessing (1) the tolerance of both plants to metal(loid)s, through the biomass production, (2) the concentrations of metal(loid)s in plant parts and (3) the concentrations of metal(loid)s in soil pore water and percolation waters. Results showed that plant growth affected soil pore water Physico-chemical properties and metal(loid) mobility. When comparing the mono- and poly-cultures, although pH was higher with the polyculture than the monoculture, the decrease in Pb mobility did not differ. Moreover, the leachate analysis showed that As concentration in the soil particles leached from the soil was higher in the polyculture condition, while Pb concentration was the highest in the willow vegetated condition. Finally, willow dry weight was not affected by the presence of clover, while clover dry weight was lower when it was grown with willow. In conclusion, the results showed that the willow and clover polyculture was not better than the monoculture of these two species for the phytomanagement of a former mine site amended with biochar.

Abstract

International audience; Metal(loid) contamination of soil, resulting from the mining activities, is a major issue worldwide, due to its negative effects on the environment and health. Therefore, these contaminated soils need to be remediated. One realistic method is the assisted phytostabilization, which aims at establishing a vegetation cover on the soil that will reduce metal(loid) bioavailability and spreading through the prevention of wind erosion and water leaching. In addition, amendments are applied to improve soil conditions and ameliorate plant growth. In this goal, biochar and compost showed good results in terms of amelioration of soil fertility and reduction in lead bioavailability. However, they usually have a negative effect on arsenic. On the contrary, iron sulfate showed capacity to reduce arsenic mobility through interaction with its iron hydroxides. Finally, the choice of the appropriate plant species is crucial for the success of assisted phytostabilization. One good option is to use endemic species, adapted to the metal(loid) stress, with a fast growth and large shoot and root systems. The aims of this study were to (1) evaluate the effects of applying biochar, compost and iron sulfate, alone or combined, to a former mine soil on the soil properties and Agrostis capillaris growth, and (2) assess the difference between two Agrostis capillaris ecotypes, an endemic metallicolous ecotype and a non-metallicolous ecotype. Results of the mesocosm experiment showed that amendment application improved soil properties, i.e., reduced soil acidity, increased nutrient availability and lower metal(loid) stress, the best being the combination biochar-compost-iron sulfate. These ameliorations allowed a better plant growth. Finally, the metallicolous ecotype performed better in terms of growth than the non-metallicolous one and could thus be used in an assisted phytostabilization process on the former mine site.

Abstract

International audience; Vegetation cover can be used in the phytomanagement of polluted areas by adding value to abandoned sites and reducing the dispersion of pollutants by erosion. Appropriate amendments, that allow both efficient plant growth and the immobilization of contaminants in the soil must be chosen in order to optimize the efficiency of this process. We used a mining technosol mainly contaminated by arsenic (1068 mg kg−1) and lead (23387 mg kg−1) to study the effect of three amendments (biochar, compost and iron grit) on (i) physico-chemical properties of the soil and soil pore water, (ii) metal(loid) mobility, bioavailability and bioaccessibility (CaCl2 and Simple Bioaccessibility Extraction Test (SBET)), and (iii) the capability of Trifolium repens to germinate and grow. All the amendments used increased the pH and electrical conductivity of the SPW, resulting in a 90% decrease in the concentration of lead in the soil pore water (SPW). We also demonstrated a decrease in Pb phytoavailability. The amendments allowed the establishment of a plant cover, although the addition of iron grit alone did not allow any clover germination. For the Pontgibaud technosol, the combination of the three amendments resulted in a significant decrease in As and Pb concentrations in clover tissues, mainly in the aerial organs. The amendments also made it possible for some of them to halve the phytoavailable fraction of arsenic. However, for compost, both the As concentrations in the SPW, and the bioavailable fraction of As increased. All the amendments used had contrasting effects on the bioaccessible fractions of metal(loid)s. The most efficient amendment combination was the addition of 5% biochar and 5% compost.

Abstract

International audience; The germination capacity of poplar seeds has never been studied in the context of metal(loid)-contaminated soils, even though poplars are present over a vast geographical area. In this study, black poplar seeds from the Loire Valley (France) were grown for 28 days in mesocosm on a heavily polluted soil that was subjected to different amendments. This phytomanagement process aimed to allow the revegetation of an As and Pb–contaminated mining soil by adding appropriate amendments, resulting in metal(loid) soil stabilisation and efficient plant growth. The objectives were to evaluate the effect of three amendments (garden soil, compost and biochar) when added alone or combined to a technosol on (i) the soil physicochemical properties, (ii) the mobility of As and Pb in the soil pore water (SPW), (iii) the capacity of poplar seeds to germinate and to grow and (iv) the metal(loid) distribution within the plant organs. The addition of amendments alone or combined allowed a 90% decrease in SPW Pb concentrations, while the arsenic concentrations were between 18 and 416 times higher. However, we were only able to obtain seed germination and plant growth on amended soils. These promising results will allow us to explore the use of such amendments in rehabilitating areas that are sources of significant metal(loid) dissemination, as well as allowing a natural plant recolonisation of these sites by seeds from the surrounding environment.

Abstract

Phytostabilization have been proposed as promising tools for long-term management of polluted sites. Optimization of the process efficiency involves choosing suitable amendments to allow both efficient plant growth and the immobilization of contaminants. The objectives of this study were to evaluate the effect of amendments on (i) the physicochemical properties of technosol and (ii) the mobility and phyto-availability of metal(loid)s. A dwarf bean growth test was conducted on technosols amended with compost, garden soil, slag and biochar. The physicochemical properties of soil pore water (SPW) were determined as well as the phyto-available concentrations of metal(loid)s by simple extraction tests. All amendments used were able to increase SPW pH and electrical conductivity, allowing a decrease in the lead concentration in SPW by 90 % and the lead phytoavailable part by 93 %. However, for all amendments, SPW As concentration increased. Lastly, the amendments improved bean growth and tended to decrease the metal(oid) concentrations in aerial organs. As concentration in roots did not decrease whereas Pb concentration decreased. Metal(loid) concentrations of Pb accumulated in the aerial parts of beans and their extractable concentrations showed a significant positive correlation with the extraction procedures. In contrast, the phytoavailable As showed a weak correlation with As concentrations in the aerial parts. The 1-M NH4NO3 extraction procedure was the most appropriate and provided the most useful indications of the phyto-availability for the studied elements.
